✦ Synopsis
Tetra(4-carboxyphenyl)-porphine iron(III) chloride ´2 CH 3 COOH ´4 H 2 O (1) was prepared via a hydrothermal synthesis approach starting from FeCl 2 and 5,10,15,20tetrakis-(4-carboxyphenyl)-21 H,23 H-porphine in glacial acetic acid in the presence of KOH as a base and ytterbium(III) acetate as a template. Compound 1 was characterized by single crystal X-ray diffraction and elemental analysis. Space group: P 1, Z = 2, unit cell dimensions at 200 K: a = 9.282(2), b = 20.239(5), c = 22.239(5) A Ê , a = 92.49(3), b = 99.87(3), c = 90.78(3)°, R 1 (observed) = 0.132, wR 2 (all data) = 0.395. The architecture of the structure is determined by interporphyrin hydrogen bonding. Four iron porphyrin units form a very wide open channel with dimensions of circa 15.7 A Ê ´15.7 A Ê . No interpenetrating is observed.
